Description

この発明は、複写機、印刷機、ファクシミリ、スキャナー等に備えられている原稿圧着板が最大開放位置から最大使用開放位置へと倒れる際の速度を緩和することができる原稿圧着板開閉装置に関するものである。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document crimping plate opening / closing device capable of reducing the speed when a document crimping plate provided in a copying machine, a printing machine, a facsimile, a scanner or the like falls from a maximum open position to a maximum use open position. It is.

複写機、印刷機、ファクシミリ、スキャナー等の装置本体には、その装置本体の上面後部に対し原稿圧着板が原稿圧着板開閉装置を介して回動可能に取り付けられている。原稿圧着板開閉装置は、一種のヒンジ機構であり、原稿圧着板をヒンジ軸まわりに回動可能に軸支して、装置本体の上面のコンタクトガラス面上に原稿圧着板を密着させることができると共に、そのコンタクトガラスを露出させることができる。原稿をコンタクトガラス面上にセットするには、原稿圧着板を回動させて（上方に移動させて）コンタクトガラス面を露出（開放）させ、そのコンタクトガラスの面上に原稿を載置した後、原稿圧着板を回動させて（下方に移動させて）、原稿圧着板で原稿をコンタクトガラス面上に圧着させることにより、原稿をコンタクトガラス面上にセットすることができる。   An apparatus main body such as a copying machine, a printing machine, a facsimile machine, or a scanner has a document pressure plate attached to a rear upper surface of the apparatus body via a document pressure plate opening / closing device. The document crimping plate opening / closing device is a kind of hinge mechanism, and can support the document crimping plate on the contact glass surface on the upper surface of the apparatus body by pivotally supporting the document crimping plate so as to be rotatable around the hinge axis. At the same time, the contact glass can be exposed. To set the document on the contact glass surface, rotate the document crimping plate (move upward) to expose (open) the contact glass surface, and place the document on the contact glass surface. The original can be set on the contact glass surface by rotating (moving downward) the original pressure plate and pressing the original on the contact glass surface with the original pressure plate.

また、原稿圧着板開閉装置には、原稿圧着板の回動を規制する原稿圧着板回動規制機構が設けられている（例えば、特許文献１参照。）。原稿圧着板回動規制機構は、通常使用時における装置本体の上面（コンタクトガラス面）に対する原稿圧着板の最大使用開放角度を６０°〜７０°に規制するものである。また、原稿圧着板回動規制機構は、装置本体の点検、修理等のメンテナンスを行う際にコンタクトガラスを容易に取り外すことができるように、コンタクトガラス面に対する原稿圧着板の最大開放角度を９０°にすることができる最大開放機能を有している。   The document crimping plate opening / closing device is provided with a document crimping plate rotation regulating mechanism that regulates the rotation of the document crimping plate (see, for example, Patent Document 1). The original pressure plate rotation restricting mechanism restricts the maximum use opening angle of the original pressure plate to 60 ° to 70 ° with respect to the upper surface (contact glass surface) of the apparatus main body during normal use. In addition, the document crimping plate rotation restricting mechanism allows the maximum opening angle of the document crimping plate to the contact glass surface to be 90 ° so that the contact glass can be easily removed when performing maintenance such as inspection and repair of the apparatus main body. It has a maximum opening function that can be

ところで、装置本体の点検、修理等のメンテナンスを行う際には、コンタクトガラス面に密着されている原稿圧着板をコンタクトガラス面に対して９０°回動させることにより、コンタクトガラス面の上方が開放された状態となり、容易にコンタクトガラスを取り外すことができることになる。すなわち、原稿圧着板が装置本体の上面（コンタクトガラス面）に対して直交する方向つまり略垂直方向に沿って立った状態であるので、容易にコンタクトガラスを取り外すことができることになる。   By the way, when performing maintenance such as inspection and repair of the main body of the device, the upper part of the contact glass surface is opened by rotating the original pressure plate that is in close contact with the contact glass surface by 90 ° with respect to the contact glass surface. Thus, the contact glass can be easily removed. In other words, the contact glass can be easily removed because the original pressing plate stands in a direction perpendicular to the upper surface (contact glass surface) of the apparatus body, that is, in a substantially vertical direction.

しかし、原稿圧着板が立った状態であると倒れることがある。その場合、最大開放位置から最大使用開放位置までの原稿圧着板に作用するトルクがゼロなので、原稿圧着板が大きな加速を伴って倒れることがあり得る。   However, it may fall over when the original cover is standing. In that case, since the torque acting on the original pressure plate from the maximum open position to the maximum use open position is zero, the original pressure plate may fall down with great acceleration.

この発明は、前記課題を解決するためになされたものであって、その目的は、原稿圧着板が最大開放位置から最大使用開放位置へと倒れる際の速度を緩和することができる原稿圧着板開閉装置を提供することにある。   SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object of the present invention is to open and close a document crimping plate that can reduce the speed when the document crimping plate falls from the maximum open position to the maximum use open position.

The speed when falling to the use release position can be reduced. That is, when the original cover is attached to the support member and the attachment member is attached to the apparatus main body, and the original cover is tilted from the maximum open position, the support member is moved from the maximum open position together with the original cover. Rotates to the maximum use release position. At this time, since the torque acting on the original cover is increased by the torque generating means, the speed when the original cover is tilted from the maximum open position to the maximum use open position can be reduced.

この発明の原稿圧着板開閉装置において、前記トルク発生手段を、前記支持部材に一方向へ摺動附勢されて取り付けられたスライダーと、前記取付部材に設けられ、前記スライダーが前記支持部材の所定回動度から当接する受け部とで構成することができる。   In the document crimping plate opening and closing device according to the present invention, the torque generating means is provided on a slider attached to the support member by being slidably biased in one direction, and the slider is provided on the attachment member. It can comprise with the receiving part which contact | abuts from a rotation degree.

この発明はさらに、前記受け部を、前記取付部材に取り付けられたカム部材に設けることができる。   The present invention can further provide the receiving portion on a cam member attached to the attachment member.

そして、この発明の原稿圧着板開閉装置においては、前記支持部材を、前記原稿圧着板に回動可能に取り付けられるように構成しても良い。   In the document crimping plate opening and closing device of the present invention, the support member may be configured to be rotatably attached to the document crimping plate.

以上説明したようにこの発明の原稿圧着板開閉装置によれば、支持部材が最大開放位置から最大使用開放位置へと回動するとき、支持部材に作用するトルクを大きくするトルク発生手段を設けたので、原稿圧着板が最大開放位置から最大使用開放位置へと倒れる際の速度を緩和することができる。   As described above, according to the document crimping plate opening / closing apparatus of the present invention, the torque generating means for increasing the torque acting on the support member when the support member rotates from the maximum open position to the maximum use open position is provided. Therefore, the speed when the original cover is tilted from the maximum open position to the maximum use open position can be reduced.

The hinge pin 11 is pivotally connected about an axis.

支持部材５は、原稿圧着板３に取り付けられるが、原稿圧着板３に回動自在に取り付けられることが好ましい。このように、支持部材５が原稿圧着板３に回動自在に取り付けられることにより、厚さが厚い原稿も装置本体２の上面に安定して密着させることができる。また、支持部材５は、装置本体２に直接取り付けてもよいが、リフト部材６を介して原稿圧着板３に取り付けられることが特に好ましい。   The support member 5 is attached to the original cover 3 but is preferably attached to the original cover 3 so as to be rotatable. As described above, the supporting member 5 is pivotally attached to the document pressing plate 3 so that a thick document can be stably adhered to the upper surface of the apparatus main body 2. Further, the support member 5 may be directly attached to the apparatus main body 2, but it is particularly preferable that the support member 5 is attached to the original cover 3 via the lift member 6.

リフト部材６は、原稿圧着板２の後端側にビス等で取り付けられる上板６１と、この上板６１の両端部からそれぞれ上板６１に対して直交する方向（略直交する方向も含む）に延びる両側板６２とから略コ字状であって支持部材５を覆うように形成されている。リフト部材６の一端部（後端部）の中央より上板６１側の箇所には第２ヒンジピン挿通孔（図示せず）が設けられていると共に、第２ヒンジピン挿通孔より他端部側で、かつ、中央より上板６１側とは反対側の箇所には作動ピン１４が挿通される作動ピン孔（図示せず）が設けられている。両側板６２の作動ピン孔に作動ピン１４が挿通されて固定されている。リフト部材６の両側板６２の第２ヒンジピン挿通孔と支持部材５の両側板５２の第２ヒンジピン孔とが軸合わせされてこれら孔に第２ヒンジピン１２が挿通されることによって、リフト部材６と支持部材５とが第２ヒンジピン１２を軸に互いに回動自在に連結されている。   The lift member 6 has an upper plate 61 attached to the rear end side of the document pressing plate 2 with screws or the like, and directions orthogonal to the upper plate 61 from both ends of the upper plate 61 (including directions substantially orthogonal). It is formed in a substantially U shape from both side plates 62 extending in a direction so as to cover the support member 5. A second hinge pin insertion hole (not shown) is provided at a position closer to the upper plate 61 than the center of one end (rear end) of the lift member 6, and on the other end side from the second hinge pin insertion hole. In addition, an operation pin hole (not shown) through which the operation pin 14 is inserted is provided at a position opposite to the upper plate 61 side from the center. The operating pin 14 is inserted and fixed in the operating pin hole of the both side plates 62. The second hinge pin insertion hole of the both side plates 62 of the lift member 6 and the second hinge pin hole of the both side plates 52 of the support member 5 are aligned with each other, and the second hinge pin 12 is inserted into these holes, so that the lift member 6 The support member 5 is coupled to the second hinge pin 12 so as to be rotatable with respect to each other.

支持部材５内には、一対のスライダー３１、３２が嵌合されている。一対のスライダー３１、３２は、断面矩形の有底筒体状に形成されている。一対のスライダー３１、３２は、互いの開口部が向き合うように支持部材５内にそれぞれ個別に摺動自在に嵌合されて、この一対のスライダー３１、３２内に圧縮コイルスプリング２１が設けられている。すなわち、スライダー３１、３２の凹状の内部が圧縮コイルスプリング２１を収容するスプリング収容部３１ｃ、３２ｃとして形成されている。圧縮コイルスプリング２１は、１個でも２個以上でもよく、例えば２個並列、或は重合して設けられ、一対のスライダー３１、３２をそれぞれ互いに離間する方向に付勢するものである。   A pair of sliders 31 and 32 are fitted in the support member 5. The pair of sliders 31 and 32 is formed in a bottomed cylindrical shape having a rectangular cross section. The pair of sliders 31 and 32 are individually slidably fitted into the support member 5 so that their openings face each other, and the compression coil spring 21 is provided in the pair of sliders 31 and 32. Yes. That is, the concave interiors of the sliders 31 and 32 are formed as spring accommodating portions 31 c and 32 c that accommodate the compression coil spring 21. One or two or more compression coil springs 21 may be provided. For example, two compression coil springs 21 are provided in parallel or overlapped to urge the pair of sliders 31 and 32 in directions away from each other.

一対のスライダー３１、３２は、取付部材４の底板４１と支持部材５（上板５１）が略平行になっているとき（例えばこの発明の原稿圧着板開閉装置１を複写機等に取り付けた場合において装置本体２の上面のコンタクトガラス面上に原稿圧着板３を密着させたとき（原稿圧着板密着時））、支持部材５内に嵌合される長さで形成されている。   The pair of sliders 31 and 32 is provided when the bottom plate 41 of the attachment member 4 and the support member 5 (upper plate 51) are substantially parallel (for example, when the original cover 1 of the present invention is attached to a copying machine or the like). In FIG. 2, when the original pressure plate 3 is brought into close contact with the contact glass surface of the upper surface of the apparatus main body 2 (when the original pressure plate is in close contact), the length is fitted into the support member 5.

先端部側のスライダー（第１スライダー）３１の底面である閉塞面３１ａの外表面は平坦面に形成されている。この閉塞面３１ａが圧縮コイルスプリング２１の付勢力によって作動ピン１４を押圧して、支持部材５とリフト部材６とが重なり合うようになっている。すなわち、圧縮コイルスプリング２１の付勢力によってリフト部材６の上板６１が支持部材５のストッパ部５５に当接して、支持部材５の上板５１とリフト部材６の上板６１とが略平行で、かつ近接するようになっている。   The outer surface of the closing surface 31a, which is the bottom surface of the slider (first slider) 31 on the tip side, is formed as a flat surface. The closing surface 31 a presses the operating pin 14 by the urging force of the compression coil spring 21 so that the support member 5 and the lift member 6 overlap each other. That is, the upper plate 61 of the lift member 6 comes into contact with the stopper portion 55 of the support member 5 by the urging force of the compression coil spring 21, and the upper plate 51 of the support member 5 and the upper plate 61 of the lift member 6 are substantially parallel. , And come close.

後端部側のスライダー（第２スライダー）３２の閉塞面の外表面の略中央部には、図１〜図７、図９に示すように、突部３３が設けられている。この突部３３は、支持部材５の上面５１に略平行に延びて形成されている。突部３３の案内板５３側は漸次傾斜された傾斜部３４として形成され、原稿圧着板密着時、突部３３が固定ピン１３に当接し、リフト部材６が第２ヒンジピン１２を軸に回動することによって、固定ピン１３が当接する箇所が突部３３から傾斜部３４に徐々に摺動する。   As shown in FIG. 1 to FIG. 7 and FIG. 9, a protrusion 33 is provided at a substantially central portion of the outer surface of the closing surface of the slider (second slider) 32 on the rear end side. The protrusion 33 is formed so as to extend substantially parallel to the upper surface 51 of the support member 5. The guide plate 53 side of the protrusion 33 is formed as an inclined portion 34 that is gradually inclined. When the original pressure plate is in close contact, the protrusion 33 abuts the fixed pin 13 and the lift member 6 rotates about the second hinge pin 12. By doing so, the place where the fixing pin 13 abuts gradually slides from the protrusion 33 to the inclined portion 34.

すなわち、装置本体２の上面のコンタクトガラス面上に原稿圧着板３が密着している状態（閉位置（図１及び図２参照））から原稿圧着板３の手前側を手に持って、装置本体２の上面から離間する方向（上方）に第１ヒンジピン１１を軸に回動させると、固定ピン１３に当接する箇所が突部３３から傾斜部３４へと徐々に摺動すると共に、第２スライダー３２が圧縮コイルスプリング２１によって支持部材５内を後端部側へと押圧されて摺動し、圧縮コイルスプリング２１が徐々に伸びる。そして、原稿圧着板３が装置本体２の上面に対する最大使用開放位置になると（図２及び図３参照）、スライダー３２の両側に設けた突起部７１が、受け部７２の手前に落ち込む際のクリック感を原稿圧着板３を介して操作者の手に感じ取ることができる。勿論、ここのところはその他の公知構成の原稿圧着板回動規制機構（図示せず）によって規制しても良い。なお、図１〜図７、図９中、３８は延出片を示し、この延出片３８と第２スライダー３２を形成する壁部との間に、案内板５３が位置されるようになっている。   That is, from the state in which the original cover 3 is in close contact with the contact glass surface on the upper surface of the apparatus main body 2 (closed position (see FIGS. 1 and 2)), the front side of the original cover 3 is held in hand. When the first hinge pin 11 is pivoted in the direction away from the upper surface of the main body 2 (upward), the portion that contacts the fixed pin 13 gradually slides from the protrusion 33 to the inclined portion 34, and the second The slider 32 is pressed and slid by the compression coil spring 21 in the support member 5 toward the rear end side, and the compression coil spring 21 is gradually extended. When the original pressing plate 3 reaches the maximum use open position with respect to the upper surface of the apparatus main body 2 (see FIG. 2 and FIG. 3), the protrusions 71 provided on both sides of the slider 32 are clicked when falling down before the receiving portion 72. The feeling can be felt by the operator's hand through the original cover 3. Of course, this may be restricted by a document pressure plate rotation restricting mechanism (not shown) having other known configurations. 1 to 7 and 9, reference numeral 38 denotes an extended piece, and the guide plate 53 is positioned between the extended piece 38 and the wall portion forming the second slider 32. ing.

原稿圧着板回動規制機構は、原稿圧着板３（支持部材５）の回動を規制するもので、原稿圧着板３の通常使用時における装置本体２の上面に対する最大使用開放角度を６０°〜７０°（略６０°〜略７０°）に規制するものである（図３及び図４参照）。また、原稿圧着板回動規制機構は、装置本体２の点検、修理等のメンテナンスを行う際にコンタクトガラスを容易に取り外すことができるように、取付部材４の両側板に設けたストッパー部４８と支持部材５の断面Ｌ形状を呈した当接部５５によって、原稿圧着板３（支持部材５）の上面に対する最大開放角度を９０°に規制することができる最大開放機能を有している（図５及び図６参照）。尚、当接部材５５は、これを支持部材５の他の個所としても良く、リフト部材６の側に設けても良い。   The original pressure-bonding plate rotation restricting mechanism restricts the rotation of the original pressure-bonding plate 3 (support member 5), and the maximum use opening angle with respect to the upper surface of the apparatus main body 2 during normal use of the original pressure-bonding plate 3 is 60 ° to It is restricted to 70 ° (approximately 60 ° to approximately 70 °) (see FIGS. 3 and 4). The document pressing plate rotation restricting mechanism is provided with stopper portions 48 provided on both side plates of the mounting member 4 so that the contact glass can be easily removed when performing maintenance such as inspection and repair of the apparatus body 2. The contact member 55 having the L-shaped cross section of the support member 5 has a maximum opening function capable of regulating the maximum opening angle with respect to the upper surface of the original cover 3 (support member 5) to 90 ° (FIG. 5 and FIG. 6). In addition, the contact member 55 may be used as another part of the support member 5 or may be provided on the lift member 6 side.

この発明の原稿圧着板開閉装置１の特徴は、支持部材５が最大開放位置から最大使用開放位置へと回動するとき、支持部材５に作用するトルクを大きくするトルク発生手段７を設けたことにある。   The document crimping plate opening / closing device 1 of the present invention is characterized in that a torque generating means 7 is provided for increasing the torque acting on the support member 5 when the support member 5 rotates from the maximum open position to the maximum use open position. It is in.

トルク発生手段７は、支持部材５に作用するトルクを大きくできれば特に限定されず、例えば、弾性部材である前記の圧縮コイルスプリング２１と、第２スライダー３２に設けられた突起部７１と、取付部材４に設けられた受け部７２とから構成されている。   The torque generating means 7 is not particularly limited as long as the torque acting on the support member 5 can be increased. For example, the compression coil spring 21 that is an elastic member, the protrusion 71 provided on the second slider 32, and an attachment member. 4 and a receiving portion 72 provided in the main body 4.

突起部７１は、第２スライダー３２の閉塞面の外表面の両側部が中央部より窪んだ段状に形成され、この両側段部３２ｂの略中央部に設けられている。突起部７１は、例えば略半円状に形成されている。受け部７２は、取付部材４の取付片４２ａの傾斜部４２ｂの略中央部に凸状に形成されており、圧縮コイルスプリング２１の付勢力によって、支持部材５が最大使用開放位置から最大開放位置までの間に位置されているときに、突起部７１が受け部７２に当接して押圧されるようになっている（図３〜図６参照）。   The protruding portion 71 is formed in a step shape in which both side portions of the outer surface of the closing surface of the second slider 32 are recessed from the center portion, and is provided in a substantially central portion of the both side step portions 32b. The protrusion 71 is formed in a substantially semicircular shape, for example. The receiving portion 72 is formed in a convex shape substantially at the center of the inclined portion 42 b of the mounting piece 42 a of the mounting member 4, and the support member 5 is moved from the maximum use open position to the maximum open position by the urging force of the compression coil spring 21. The protrusion 71 comes into contact with and is pressed against the receiving portion 72 (see FIGS. 3 to 6).

このように、圧縮コイルスプリング２１の付勢力によって突起部７１が受け部７２に当接して押圧されることにより、支持部材５（原稿圧着板３）が最大開放位置（図５及び図６参照）から最大使用開放位置（図３及び図４参照）へと回動するとき、支持部材５（原稿圧着板３）に作用するトルクが大きくなる。従って、この発明の原稿圧着板開閉装置１は、原稿圧着板３が最大開放位置から最大使用開放位置へと倒れる際の速度を緩和することができる。   Thus, the protrusion 71 is brought into contact with and pressed against the receiving portion 72 by the urging force of the compression coil spring 21, so that the support member 5 (document pressing plate 3) is at the maximum open position (see FIGS. 5 and 6). The torque acting on the support member 5 (document pressing plate 3) becomes large when rotating from the maximum use release position (see FIGS. 3 and 4). Therefore, the document crimping plate opening / closing device 1 of the present invention can reduce the speed when the document crimping plate 3 falls from the maximum open position to the maximum use open position.

また、第２スライダー３２の両側段部３２ｂの支持部材５の上板５１側には、湾曲状に窪んだ凹部３６が設けられている。この凹部３６は、取付部材４の取付片４２ａの先端部が面接触する凹状に形成されている。この凹部３６は、支持部材５（原稿圧着板３）が最大開放位置（図５及び図６参照）に達したとき、取付片４２ａの先端部が面接触するように形成されている。これにより、支持部材５（原稿圧着板３）が最大使用開放位置（図３及び図４参照）から最大開放位置（図５及び図６参照）へと回動したとき、取付片４２ａの先端部が面接触するので、支持部材５（原稿圧着板３）が安定した状態で立たせることができる。   In addition, a concave portion 36 that is recessed in a curved shape is provided on the side of the upper plate 51 of the support member 5 of the side step portions 32 b of the second slider 32. The recess 36 is formed in a concave shape in which the tip of the mounting piece 42 a of the mounting member 4 is in surface contact. The recess 36 is formed so that the tip of the mounting piece 42a comes into surface contact when the support member 5 (original pressure plate 3) reaches the maximum open position (see FIGS. 5 and 6). As a result, when the support member 5 (document pressing plate 3) is rotated from the maximum use open position (see FIGS. 3 and 4) to the maximum open position (see FIGS. 5 and 6), the tip of the mounting piece 42a. Because of the surface contact, the support member 5 (original pressure bonding plate 3) can stand in a stable state.

また、この発明の原稿圧着板開閉装置１は、厚さに関係なく原稿を装置本体２の上面に安定して密着させることができる。   Further, the original cover 1 according to the present invention can stably adhere the original to the upper surface of the apparatus main body 2 regardless of the thickness.

すなわち、圧縮コイルスプリング２１の付勢力によってリフト部材６の上板６１が支持部材５のストッパ部５５に当接して、支持部材５の上板５１とリフト部材６の上板６１とが略平行で、かつ近接するするので、リフト部材６の後端部が下方に回動することがない。このため、原稿圧着板３を持ち上げて装置本体２の上面のコンタクトガラス面に原稿を載置する場合、通常、原稿圧着板３のリフト部材６が取り付けられている箇所とは反対側の端部又はその近傍等に設けられている把持部を持って原稿圧着板３を上方に持ち上げると、原稿圧着板３は第１ヒンジピン１１を軸にのみ回動してコンタクトガラス面が外部に露出する。その露出したコンタクトガラスの面上に原稿を載置する。   That is, the upper plate 61 of the lift member 6 comes into contact with the stopper portion 55 of the support member 5 by the urging force of the compression coil spring 21, and the upper plate 51 of the support member 5 and the upper plate 61 of the lift member 6 are substantially parallel. And the rear end portion of the lift member 6 does not rotate downward. For this reason, when the original cover 3 is lifted and the original is placed on the contact glass surface of the upper surface of the apparatus main body 2, the end of the original cover 3 opposite to the portion where the lift member 6 is attached is usually provided. Alternatively, when the document crimping plate 3 is lifted upward by holding a grip portion provided in the vicinity thereof, the document crimping plate 3 rotates only about the first hinge pin 11 and the contact glass surface is exposed to the outside. An original is placed on the exposed contact glass surface.

載置後、持ち上げた原稿圧着板３を降ろすと、原稿圧着板３はコンタクトガラス面と接触する方向に第１ヒンジピン１１を軸に回動する（下方に移動する）。このとき、圧縮コイルスプリング２１の付勢力によってリフト部材６の上板６１が支持部材５のストッパ部５５に当接した状態のまま、つまり、原稿圧着板３（リフト部材６）が第２ヒンジピン１２を軸に回動することないまま、原稿圧着板３が移動する。   After the placement, when the raised original cover 3 is lowered, the original cover 3 rotates about the first hinge pin 11 in the direction in which the original cover 3 contacts the contact glass surface (moves downward). At this time, the upper plate 61 of the lift member 6 is in contact with the stopper portion 55 of the support member 5 by the urging force of the compression coil spring 21, that is, the original cover 3 (lift member 6) is in the second hinge pin 12. The original cover 3 moves without rotating around the axis.

このとき、コンタクトガラス面に載置されている原稿が紙のように厚さが薄い場合には、原稿圧着板３は、紙に接触するときには面接触する。その結果、原稿の全体が原稿圧着板３に接触して原稿がコンタクトガラス面に押し付けられるので、原稿が安定してコンタクトガラス面に密着することになる。   At this time, when the original placed on the contact glass surface is as thin as paper, the original cover 3 comes into surface contact when contacting the paper. As a result, the entire document comes into contact with the document crimping plate 3 and the document is pressed against the contact glass surface, so that the document is stably adhered to the contact glass surface.

原稿が図７に示すように本のように厚さが厚い場合、原稿圧着板３を回動させる（下方に移動させる）と、原稿８０の支持部材５側の端部８０ａ又はその近傍に原稿圧着板３の支持部材５の近傍の一部が接触し、原稿８０の支持部材５側の端部とは反対側の端部と原稿圧着板３との間に空間が形成される。すなわち、把持部側の端部の原稿圧着板３は浮いた状態となる。その浮いている原稿圧着板３の例えば把持部側の端部近傍をコンタクトガラス面側に押圧すると、作動ピン１４が第１スライダー３１を第２スライダー３２側に押圧して圧縮コイルスプリング２１の付勢力に抗して第１スライダー３１が第２スライダー３２側に移動すると共に、原稿圧着板３（リフト部材６）が第２ヒンジピン１２を軸に回動する。すなわち、原稿８０の上部を覆うように原稿圧着板３が移動する。例えば、その原稿８０の上部が平坦面である場合には、この上部に原稿圧着板３が面接触する。よって、厚さが厚い原稿８０が安定してコンタクトガラス面に密着することになる。   When the original is as thick as a book as shown in FIG. 7, when the original pressing plate 3 is rotated (moved downward), the original 80 is located at or near the end 80 a on the support member 5 side of the original 80. A part of the pressure-bonding plate 3 near the support member 5 comes into contact, and a space is formed between the end of the document 80 opposite to the end on the support member 5 side and the document pressure-bonding plate 3. That is, the document pressing plate 3 at the end on the gripping portion side is in a floating state. When, for example, the vicinity of the gripping portion side end of the floating original cover 3 is pressed toward the contact glass surface, the operating pin 14 presses the first slider 31 toward the second slider 32 and the compression coil spring 21 is attached. The first slider 31 moves to the second slider 32 side against the force, and the original cover 3 (lift member 6) rotates about the second hinge pin 12. That is, the original cover 3 moves so as to cover the upper portion of the original 80. For example, when the upper part of the original 80 is a flat surface, the original cover 3 comes into surface contact with the upper part. Therefore, the thick original 80 is stably adhered to the contact glass surface.

従って、この発明の原稿圧着板開閉装置１は、厚さに関係なく原稿を装置本体２の上面に安定して密着させることができる。   Therefore, the document pressing plate opening / closing device 1 of the present invention can stably adhere the document to the upper surface of the apparatus body 2 regardless of the thickness.

尚、トルク発生手段は、当接部５５に相当する部分を、取付部材１０から独立して別体に設けたカムピンと一体に形成したカム部材とすることができる。そして、このカム部材は、カムピン１３と別体に構成しても良い。   The torque generating means can be a cam member in which a portion corresponding to the contact portion 55 is formed integrally with a cam pin provided separately from the mounting member 10. The cam member may be configured separately from the cam pin 13.

以上詳細に説明したようにこの発明は、簡単な構成で、とくに複写機の原稿自動送り装置付きの重量のある原稿圧着板開閉装置に実施して好適である。   As described above in detail, the present invention has a simple configuration, and is particularly suitable for application to a heavy document pressing plate opening / closing device equipped with an automatic document feeder of a copying machine.
